Things haven't been perfect for Bluesky; the platform has had some hiccups, seemingly due to the influx of people, and one major outage due to a cut fiber cable. But Meta has clearly been feeling the heat.

Last week, the day after Bluesky touted its 15 million total users, Threads boss Adam Mosseri shared that Threads had already surpassed 15 million signups for November alone. (CEO Mark Zuckerberg recently shared that the platform has 275 million monthly users.) And Meta has aggressively introduced some significant Threads changes, including its own version of custom feeds, a major change to make the For You feed show more from people you follow, and some big improvements to search.
